Temperament:
Decker Terriers are multipurpose hunting dogs but also an outstanding companion. They tend to be less aggressive than Jack Russells; while they have a definite terrier personality they also have an "off switch" and love lounging on the sofa in a lap as much as tearing about the yard. Decker Terriers are normally cheerful dogs but they tend to be more sensitive and at times calmer than Jack Russells to changes in their environment, owner's moods, or to unexpected noises, people, and activities. The "social sensitivity" of Decker Terriers makes them very trainable and easier to live with for the average pet owner but it also means that extensive socialization from an early age is critical. Proper socialization of a terrier puppy includes exposing the animal to a wide variety of people and places, particularly during the first 3 months of life. Like most active and intelligent breeds, Decker Terriers tend to be happier when they receive a great deal of mental stimulation and exercise.

Grooming:
The Decker Terrier is easy to groom. An occasional combing and brushing to remove dead hair is all it needs.

Exercise:
Decker terriers are very active dogs by nature. They enjoy indoor or outdoor playing and rather long walks. They also love time to run in an off leash area. The have great stamina and are bred for sprinting. They are especially fond of having a large yard to run around in. Though they're not usually escape artists, you should still make a point to double check the integrity of your fence, since they can slip through holes and enjoy hunting.

Living Condition:
They are fairly active indoors and should have at least a small to medium sized yard. Provided you have the proper fencing, they are able to spend a good amount of time outdoors. They love to be inside the house and outside to play.
